Not-So-Low Lowering Springs For The Gen4 Mazda 3 Turbo

Since releasing our original turbo springs for the Mazda 3, we have noticed that some people would like lowering springs for their Mazda 3 Turbo that offer a milder drop in ride height, but still provide the same great handling characteristics as the originals. This is the reason behind the new CS lowering springs for the turbo Mazda 3; the “Not-So-Low” springs. The drop in ride height has been reduced 0.5 inches in the front and 0.3in in the rear and offers another option for those wanting lowering springs for their Turbo Mazda 3. Keep on reading to get a look at the new CS lowering springs in action.

First let’s go over the main difference between the new CS lowering springs and the original ones. Ride height is increased 0.5 inches over the previous lowering springs in the front and 0.3 inches in the rear which brings the total drop to 1.0 inch in the front and 1.5 inches in the rear for hatchback models. The slightly heavier sedan nets a total drop of 1.0 inch front and 1.6 inches in the rear. The sedan sits just slightly lower in the rear because of the extra weight, but also sits level and looks fantastic! The milder drop in ride height still looks low enough to give your Mazda an aggressive stance, b

Now onto the benefits of the CS lowering springs that you can feel. The improvement in handling that you get from the CS lowering springs really helps bring some much needed sharpness to the Mazda 3 Turbo. Lowering the height of the car also results in the center of gravity being lower, which helps reduce the amount of body roll felt while driving. Also in conjunction with this, is the increased spring rates, which also play a major part in reducing body roll while cornering. This gives you more confidence while driving at the limit. We have also adjusted the rear spring rates to help reduce understeer when pushing your car to the edge and helps give it more neutral handling characteristics.

For the new CS lowering springs we have retained the proven spring rates from the original lowering spring kit. This results in a front spring rate of 3.4K while the rear has a spring rate of 5.9K. This gives you a great balance of still being able to enjoy daily driving while also giving you a sportier feel when hitting the backroads. The Turbo Mazda 3 also features stiffer dampers that control the extra weight added by the turbo better so the ride is smooth and not bouncy.

These springs also feature the same simple installation of the original kit and only require modification to the factory bump stops so that proper suspension travel is retained at the lower ride height. The springs are made with high tensile strength spring steel to ensure that they perform consistently and will not settle over time. The springs are then powdercoated black to provide a durable finish and protect against corrosion. They also feature spring silencers to prevent any additional noise during suspension travel.

The Performance Rear Motor Mount For 4th Gen Mazda 3 is Ready For Action

If you’re looking for a performance part for your Gen 4 Mazda 3 & CX30 to elevate the driver experience then the CorkSport Rear Motor Mount. This CS RMM is designed to fit any 2019+ Mazda 3 & CX30 whether it is AWD or FWD, Turbo or NA, MT or AT. The key focal point for this RMM is to offer the driver additional feedback for what the car is doing when driving hard. The CS RMM helps eliminate the excessive engine movement, increase throttle response and provide a more solid shifter feel if you have a car with a stick.

Starting with the main body of the CorkSport RMM, it is manufactured from A356-T6 aluminum to provide a robust and light weight mount that effectively replaces the quite large and heavy OEM mount. The factory mount features a large rubber center section which contributes to the excessive engine movement and additional weight. For the CS RMM we decided to add smaller bushings towards the front and back of the mount which allowed us to save material and weight.  Below you can see the two RMM’s compared against one another.

Now onto the polyurethane bushings, which play a big role in the increased driver feedback and reduction in engine movement. We tested the selected 70A bushings extensively and found that they offer a good combination of providing both a noticeable improvement in the driving experience while not introducing to much extra noise, vibration, and harshness (NVH) into the mix for daily driving.

NOTE: NVH (noise, vibration, harshness) is a standard term used in the automotive industry.  NVH is a byproduct of changing some OEM components to aftermarket components in the pursuit of focused performance. Example of components that can increase NVH: engine mounts, clutch/flywheel, intake, exhaust, suspension, tires/wheels…and many more. 

During the first stage of testing we started out with only two poly bushings in the front of the RMM, but after further testing we found that adding an additional two bushing to the rear of the RMM provided much lower NVH while still reducing engine movement considerably.

The last piece that is fundamental in the CS RMM is the bushing sleeves. The sleeves provide the ability to install hardware through the polyurethane bushing without having the bushing itself compress and possibly crack when applying torque to the bolt and instead transfer the force into the sleeve. The bushing sleeves are precision machined out of steel for strength and then zinc coated so they will not corrode over time and wear out the polyurethane bushing prematurely.

Ok, so now how does the CS RMM improve the driver experience? Well, the factory RMM allows the motor to rotate a good amount which helps provide a smooth driving experience for around town, but this increase in engine movement decreases the throttle response and shifter feel.

This is because the motor is allowed to rotate a certain amount before the wheels do, so by decreasing the amount the motor has to rotate, allows the wheels to start rotating sooner, thus increasing the responsiveness of the car. This reduction of movement also provides a better shifter feel if you have a manual because there is less movement between the connection of the shifter and transmission.

What to expect from the Rear Motor Mount:

From our testing in multiple R&D cars and beta tester cars and the thousands of miles driven…it’s awesome!  From about 2000rpm up to redline you are going to feel a smooth engine that loves to give you feedback on your throttle, shifting and engine braking.  Below 2000rpm to idle you may notice some vibration, especially when the A/C pump is in operation. 

Thanks for checking out the CorkSport Rear Motor Mount for the 4th Gen Mazda 3 & CX30! If you want to add this mod to your Mazda and get all the benefits discussed above, be sure to head over to the product page for more details.

Announcing The Turbo Kit 80mm GEN3 2014-18 Mazda 3 Cat Back Exhaust

SkyActiv Mazda 3 Cat Back Turbo Exhaust Kit

Around 3 years ago the 80mm Cat Back Exhaust was released for the 3rd Gen Mazda 3. During this time many have enjoyed the increased sound, performance and looks that it offers. As we have been developing the Turbo Kit for the 2.5L 3rd Gen Mazda 3, we have also had a chance to refine and tune the 80mm Cat Back Exhaust to further improve the tone and sound of the exhaust while reducing drone for 3’s equipped with the Turbo Kit. That is why we are excited to release the Turbo Kit specific 80mm Cat Back Exhaust to those of you who have or are looking to pick up the Turbo Kit for your 2014-2018 2.5L Mazda 3.

2014-2018 Mazda SkyActiv Turbo Exhaust

With the original 80mm CBE installed on our Turbo Kit equipped Mazda 3, we found that while the sound was good, the drone it created in the cabin was too aggressive for our liking. To combat this we tested multiple different combinations of midpipes and axle backs with different resonator configurations to find the best solution. From this testing we found that the combo that worked best was to keep the same midpipe setup, but to modify the axle back so that no resonators were used. This resulted in a substantial reduction in drone while adding in a more aggressive tone at higher RPM’s. With that being said if you are upgrading from a stock or 60.5mm exhaust it will be a large increase in NVH (Noise, Vibration, and Harshness) but this is offset in our opinion by the tons of fun noises it offers. Since the axle back is the only component that has been changed for the Turbo Kit specific exhaust, if you already have an 80mm CBE and want to upgrade, all you have to get is the non-resonated axle back to take advantage of the reduced drone and improved sound. To get a good idea of how the 80mm CBE will sound during different driving conditions, check out the video below.

Aftermarket Turbo Back Exhaust Mazda3 2014-2018

The Turbo Kit 80mm CBE also provides the same great appearance of the original 80mm CBE. Both the sedan and hatchback exhausts feature 100mm or ~4” tips. On the hatchback this helps fill out the bumper cutouts and the slant cut design helps them match the flow of the bumper profile. The sedan on the other hand, features a single wall design so that water and other debris don’t get caught in the tip since they are hidden behind the bumper and angled down. No matter which model you have, these features help the rear of the car stand out and provide an aftermarket look that is subtle and classy as it should have been from the factory.  

Performance Turbo 2014-2018 Mazda3 Exhaust

The great build quality and material are also carried over from the original 80mm Cat Back Exhaust with the use of T-304 stainless steel that is polished to a mirror like finish. This helps keep the CBE looking new and protects against corrosion for a long time to come. All joints are TIG welded to ensure durability along with a nice appearance. The resonators use a flow-thru design so exhaust flow remains uninterrupted while drone is kept down. Check out the product page for more pictures and details on the Turbo Kit 80mm CBE.

New Product – Mazda 3 Hatchback Rear Spoiler 2019+

Enjoying your 4th GEN Mazda 3 but wanting to change up the look? Introducing the CorkSport Performance Spoiler for 2019+ Mazda 3 Hatchback. We went for an OEM+ design that incorporates the great fitment and lines of the OEM aero kit spoiler but in a much more aggressive package. Taller, longer, and with an upturned rear edge, the CS spoiler add some much needed sportiness to the look of your 3. Available in multiple finishes to suit your budget and build, the CS spoiler is a great next mod for your build! Read on for more details and check out the product listing here to purchase.

We like the OEM spoiler but were disappointed at how insignificant it looks when installed, especially when paired with the fairly aggressive OEM front lip & rest of the aero kit. The CorkSport Spoiler takes design cues from the OEM aero kit spoiler however, the design is unique to CorkSport. We started from scratch and polled the community for design opinions before settling on a final design that is both higher off of the rear hatch than OEM and extends further rearward than OEM. The design is finished off with an upturned rear edge for a great “duckbill” style look which is aggressive without being too much. You’ll be turning heads, especially when paired with CorkSport Lowering Springs and a nice set of wheels!

Fitment was equally important as aesthetics when we designed the CS spoiler. We 3D scanned an OEM aero kit wing to get the exact mounting surfaces and edge profiles so that the CS version fits just as good as OEM. We use the same mounting locations as OEM as well. This means no drilling if you’re switching from OEM aero kit to CorkSport spoiler. If you do not have the OEM spoiler you do have to do some drilling, however, Mazda pre-marks the holes for a relatively easy install! By using the same mounting locations and more adhesive mounting tape than OEM, you can be sure your CorkSport spoiler won’t be going anywhere!

2021 Mazda 3 Turbo Duckbill spoiler

The CorkSport Mazda 3 spoiler is offered in three finishes so you can choose what is best for your build. Each option uses a fiberglass base with different top layers. Regular woven carbon fiber, forged carbon fiber, and basic black fiberglass are each available. The carbon fiber options feature a UV resistant epoxy top coat for great protection from the elements and a mirror like finish. The full fiberglass option comes in a satin black coat with some light scratches and will require some finishing. We recommend some finish sanding and a final layer of paint or wrap. The shape is the same for each unit however the purchase price varies so you can really choose the best option for your build & budget.

3 options of Mazda 3 rear wing finish

Finally, each CorkSport spoiler comes with all the hardware and accessories needed for installation. This includes mounting bolts, washers, mounting tape, and rubber washers for waterproofing. We even include new replacement OEM Mazda clips that almost always break with removing the upper trim panel on the hatch! All of this comes with full color install instructions and great customer service & support!

2021 Turbo Mazda 3 spoiler fits with the body style well

So if you’re ready to take your GEN4 build to the next level, check out the CorkSport Performance Spoiler for 2019+ Mazda3. We think it’s what the OEM spoiler should’ve been and you will not be disappointed! Don’t be shy to contact us with any questions!
